Title: Refrigerating air conditioner
Inventor: NAKAYAMA MASAHIRO
IPC: F25B13/00
Filed: 2000-02-17
Abstract: PROBLEM TO BE SOLVED: To provide a refrigerating air conditioner of which refrigerant is combustible but has a small risk of depletion of the ozone layer as such refrigerant as R32, R290 or the like which has filled a refrigerant with small GWP, and at the same time has secured safety by reducing the amount of the filled refrigerant. SOLUTION: A combustible refrigerant is used, and at the same time the opening of a refrigerant flow rate-controlling device or the capacity of a compressor is controlled so that the degree of supercooling of the refrigerant at the outlet of a condenser can be set to an optimum value (5-20 deg.C for R32, and 5-17 deg.C for R290). Also, for example, a container for storing the refrigerant in a refrigerant circuit is abolished, the number of paths at the outlet side of the condenser is reduced, or the diameter of a heat transfer pipe at the outlet side of the condenser is reduced, thus reducing the capacity of a part where a liquid refrigerant stays.

Abstract: PROBLEM TO BE SOLVED: To provide a radar device capable of demodulating without being influenced by the output fluctuation of a frequency-modulated transmit signal. SOLUTION: An oscillator 11 outputs a frequency-modulated radio wave to a switching circuit 12 through a directional coupler 13. The switching circuit 12 modulates the radio wave by switching and emits it from a transmitting antenna 14. A transmit signal emitted from the transmitting antenna 12 is reflected by an obstruction and received by a receiving antenna 21. A mixer 22 mixes the input signal and a local signal from the directional coupler 13 and outputs a mixed signal S1 to a high-pass filter 23. The filter 23 eliminates the output fluctuation noise of low frequency generated in the frequency modulation of the oscillator 11 included in the mixed signal S1. A mixed signal S2 from which noise is eliminated, is demodulated by a switching demodulating circuit 25 through an AC amplifier 24.

Title: Computer system
Inventor: KITAMURA ATSUSHI
IPC: H04L12/28
Filed: 2000-03-09
Abstract: PROBLEM TO BE SOLVED: To set a priority code string in its optimum range. SOLUTION: A parameter deciding part 28 confirms whether the resources sufficient to hold the information necessary for transmission are available. When the resources are found sufficient, parameters σand μ which are used for deciding the priority code string of a probability distribution function are set to their initial values. When the resources are not sufficient, the value of σis reduced while the value of μ is increased and these value are held at a parameter holding part 25. Then (n) pieces of uniform random numbers are generated by a uniform random number generation part 23. A probability distribution generation part 24 calculates a prescribed probability distribution function from the value held at the part 25 and the uniform random numbers generated by the part 23. Thus, the priority code string is decided from a certain distribution and then generated.
